6) Cassie and Gabby are selling pies for a school fundraiser. Customers can buy apple pies and lemon pies. Cassie sold 6 apple pies and 4 lemon pies for a total of $80. Gabby sold 6 apple pies and 5 lemon pies for a total of $94. What is the cost of each pie?​


I need help plz

Answers

Answer:

Explanation:

Cassie sold 6 apple pies and 4 lemon pies for 80$

Gabby sold 6 apple pies and 5 lemon pies for 94$

They both sold 6 apple pies but gabby sold 1 lemon pie more than Cassie and her total increase by 14$. Thus, we can say that 1 lemon pie = 14$.

If 1 lemon pie = 14$ then 5 lemon pie = 14 x 5 = 70$

And:
6 apple pies + 70$ = 94$
6 apple pies = 94 - 70
6 apple pies = 24
1 apple pie = 24/6 = 4$

Therefore, 1 apple pie = 4$ and 1 lemon pie = 14$

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50

Answers

Answer:

A: Negative cash flow, $50

Step-by-step explanation:

Bob makes $3000 a month.

Every month he has to pay $950:

3000 - 950 = 2050

Pay an additional $250:

2050 - 250 = 1800

And another additional $1850:

1800 - 1850 = -50

Therefore, he has a negative cash flow of $50 a month.

Which statements are true regarding the sides and angles of the triangle? Select three options. Line segment X Y is the longest side. Angle X is the largest angle. Angle Z is greater than angle Y. Line segment X Z is opposite the largest angle. Line segment X Z is the shortest side.

Answers

Answer:

B. Angle X is the largest angle.

C. Angle Z is greater than angle Y.

E. Line segment X Z is the shortest side.

Step-by-step explanation:

YZ = 2n, XZ = n - 2, XY = n + 4 and n ≥ 5.

YZ - XZ = 2n - (n - 2) = n + 2. but n ≥ 5, hence YZ - XZ = n + 2 ≥ 7.

YZ > XZ

YZ - XY = 2n - (n + 4) = n - 4. but n ≥ 5, hence YZ - XY = n - 4 ≥ 1

YZ > XY

XY - XZ = n + 4 - (n - 2) = 6: XY > XZ

Therefore:

YZ > XY > XZ

The angles are proportional to their opposite sides, hence:

∠X > ∠Z > ∠Y

A. Line segment XY is the longest side.

This is wrong because YZ is the longest side.

B. Angle X is the largest angle.

This is correct. ∠X is the largest angle because it is opposite to the longest side (YZ)

C. Angle Z is greater than angle Y.

This is correct. ∠Z is opposite to the side XY while ∠Y is opposite to the side XZ

D. Line segment XZ is opposite the largest angle.

This is wrong. ∠X is the largest angle which is opposite to the longest side (YZ)

E. Line segment X Z is the shortest side.

This is correct

A group of biologists found a total of 28 loggerhead turtle nests along a beach during a certain season. This was 40% of the total number of turtle nests the group found during that season. What was the total number of turtle nests the group found during that season?

70
85
110
143

Answers

110 I believe is the answer

Answer:

A

Step-by-step explanation:

Let T represent the total number of turtle nests found during the season.

The 28 turtle nests was 40% of 0.4 of the total. Therefore:

[tex]28=0.4T[/tex]

So, to find T, divide both sides by 0.4:

[tex]T=70[/tex]

So, the total number of turtle nests the group found during tthe season was 70.

Hence, our answer is A.

Answer:

An equation for the parabola would be y²=-19x.

Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis.  This means we will use the standard form

(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.

Beginning with the directrix:

x=h-p=4.75

h-p=4.75

Since the vertex is at (0, 0), this means h=0 and k=0:

0-p=4.75

-p=4.75

p=-4.75

Substituting this into the standard form as well as our values for h and k we have:

(y-0)²=4(-4.75)(x-0)

y²=-19x

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.

(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.

What is velocity?

Velocity is the rate of change of displacement with time. The velocity of the  cars depends on displacement and time of motion.

First velocity of the car at the 0.25 meter mark

The first velocity is calculated as follows;

v1 = 0.25 m / t1

let t₁ = 2 s

v₁ = 0.25/2

v₁ = 0.125 m/s

Second velocity of the car at the 0.5 meter mark

v2 = 0.25 m / (t2 – t1)

let t₂ = 3 s

v₂ = 0.25(3 - 2)

v₂ = 0.25 m/s

The complete question is below:

Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
